CAR-ROOF.

Specification of Letters Patent.

Application filed January 29, 1919. Serial No. 273,824.

the roof sheets are mounted for pivotal movement at their eaves and corners.

The invention consists further inproviding'a stop at the eavesf'or the eaves corners ot the roof sheets on which the sheets pivot.

Further objects4 and particulars of the invention will appear in connection with the following description and the accompanying drawings.

In the drawings:

Figure l is an enlarged detail transverse sectional view of' a ca'r root' on the line l-l Fig. 2, the running board saddle being in elevation.

Fig. 2. is a detail top plane view of a car roof embodying my invention.

v Fig-3 is an enlarged detail sectional view on the line 3--3 Fig. 2.

Fig. -l is an enlarged detail sectional view showing the flexible joint between the roof or plate and the flashing at the eaves ot' the car.

The reference numeral l designates a suitable ridge pole and 2 designates suitable roof' sheathing on which the roof plates are bodily movably mounted. lt will be seen 'from the drawings that the joints between the side marginal edges ot the sheets, at the eaves, and at the ridge al'e loose flexible joints whereby the sheets or Vplates are tree to move bodily to compensate for service movements without buckling or otherwise distorting tbe sheets or plates,

'l'he side marginal edges olj the roo f` sheets 2l are provided with' upstanding relient flanges which interlock` with a loose. flexible joint with tli'e re-bent side marginal flanges of' the seam cap 5. A mullion is positioned under the seam cap 5 and between the side marginal edges ot the root sheets or plates so that said plates are free to move relatively to said mullion.

'lhe loose flexible joint between the roof loverlying the roof plates.

sheets 2 and the flashing 3a is clearly shown i in Fig. el.

The ridge end of the root' sheets or plates is re-bent, the portion (i of said bend overlying the upper face of the root' plate. A filler strip 7 1s suitably secured within Said re-bend with its edge projecting beyond the Patented June 15,1920.l

edge of the re-bend whereby the possibility of' the edge of' there-bend cutting or chafing the ridge cap is eliminated.

The ridge lap Sis provided with downwardly projecting side flanges 9 which ter' minate in 4a lateral flange l0, said flange 10 lt will be seen from Fig, l that the ridge ends of' the sheets or plates on opposite sides of the ridge are spaced from each other whereby the sheets or plates are tree to move toward each other at the ridg and are t'ree Vto move relatively to each other.

ln order to relieve the side flanges 9 of the ridge cap of stresses in the the direction of' the eaves, l support the roof:l plates at their outer corners at the eaves. l secure roof clips or stops ll to tlie side 'all structure of: the car. which clips extend upwardly and over the metal root' structure and prevent the root plates from moving bodily toward the eaves and maintain the filler blocks in spaced relation to the flanges 9 of the ridge cap.

The fillers T constitute or function as a rigidif'ying member extending from side to side of the roof plates and maintain the ridge end of the roof plates flat and prevent buckling or distorting of the ridge end of the rootl plate, whereby slip joint between the ridge cap and plate is Inaintained iree, All joints in the metal roof structure are weather proof.

rlhe root shown herein is designed to accommodate itself to service movements of the car.

The loose joints between the seam caps 5 and roof sheets or plates 3 permit the sheets to move bodily on the roof sheathing without being distoipte'd or injuring the joint between them and the seam caps. In some instances the movemen of the-car is such that the rOot'sheets are caused to move tangent to the mullions in which movement one` or the. other of the eaves corners of the roet sheet is loosely pivoted on the closed end of the seam cap said closed end functioning as a f'ulerum for the sheet. The outer end of' L* the seam cap` resting against any suitable Matter shown but not claimed in this case is claimed in my application led January 29, 1919, Serial No. 273,823.

Vhat I claim is 1. In a car, a roof including a sheathing,

'15 metal plates bodily movably mounted on said sheathing and .spaced apart at the ridge and along their side marginal edges, a mullion between adjaent sheets, a seam cap over said mullions and side-edges of the fplates the side edges of the plates having play between the mullions and caps, said `ca s'being provided with an endv wall at their eaves end, which constitutes a stop to limit their outward movement of the plates, clips Asecured to the side wall struc- A*tureof the car and projecting upwardly and ,inwardly over said seam caps, the end wall vvof the seam caps constituting pivot points forthe'plates, an open return bend at'the' v$0 ridge 'end of ythe plates overlying and spaced freine the upper face of the plates, a ller seciiie'dinsaid bend and extending therein apoximately the width of the plate, a ridge side flanges', on said ridge cap extending downward tothe late; said bend vand rbein loosel 4con ned within the cap 'an jspace from lthe said side "b 'meenwfsalid Sto caig'ffa roof including a sheathing,

bodily movably mounted there- `attached thereto a rigidifying iriclesiir'ig,ser' element vand ,overlying the rdge'end' of the plate and "theridge' end o the plates eX-H "verse'ly thereof, a ridge cap' spaced therefrom, stops at the eaves end of the plates functioning to space said rigidifying element from the ridge cap and 'as I pivots for the eaves end of the plates on which the platespivot to accommodate serV- ice movements of the car whereby the plates will not buckle on tear said rigidifying element having a floating movement in the ridge cap.

3. In a car, a roof including a sheathing,

metal plates bodily movablymounted on said sheathing and spaced apart attheir ridge and side marginal edges,a seam cap over the side marginal edges of the sheets permitting free bodily movement of the sheets, a stop at the eaves end of the seam cap upon which the eaves corners of the roof sheets may pivot, a ridge cap extending over the ridge endA portions of the roof sheets and a filler in the ridge end Aof the roof sheets which is free to vslide within the cap as the sheets move to accommodate car service movements without imposingv strain upon the parts.

4. In' a car, a roof including a sheathing, 70 `'metal roof platesr bodilymovably mounted on said sheathing and spaced apart at the ridge and along their side marginal edgesa seam cap over the side marginal edges of the sheets permitting free bodily movements of the sheets, a stop at the eaves end of the seam cap upon which the eaves corners of the sheets may pivot, a hollow ridge cap having side walls, a filler in the rid e endof the sheets positioned within an nors0 mally spaced from the 'side walls of the ridge cap,` whereby said sheet may freely move within said cap without limposing strain upon the roof sheets.
